Title: Method for separation of thin film piece
Inventor: MADOKORO SHIYOUJI
IPC: C23F1/00
Filed: 1983-01-17
Abstract: PURPOSE:To separate a thin film piece easily in a short period by a method wherein the film of material which will be dissolved well by a diluted HF solution is deposited on a semicondutor substrate as a base film, a metal or a semiconductor film is superposed thereon, soaked in the diluted HF solution, and the base film is dissolved. CONSTITUTION:A Ti film 10 is vapor-deposited approximately 500Angstrom  on an Si substrate, and an Al film 2 is deposited approximately 1,000Angstrom . When the above is soaked in the diluted HF solution 11 of 50% HF:H2O=1:200, the film 10 disappears within a minute because Ti has an extremely high rate of etchsing by HF, and the Si substrate 1 and the Al film 2 can be separated easily. Besides, as the constitution of Mo/PSG/Si or Si thin film/CVD-SiO2-film/Si substrate has a very high rate of etching of a base film for diluted HF, it contributes greatly on the formation of thin film pieces. The material of substrate is not limited to Si.

Title: Operation control method for herium liquifying freezing device
Inventor: SATAKE HIROMASA
IPC: F25J1/00
Filed: 1989-01-10
Abstract: PURPOSE:To keep a flow rate in case of a pre-cooling operation and shorten a pre-cooling time in a herium liquefying refrigerator by a method wherein a JT valve having a two-stage motion mechanism is applied in operation of this refrigerator without damaging a controlling characteristic during a rated operation. CONSTITUTION:A herium liquefying refrigerator is composed of a compressor 1, a cold box 2 and a storing tank 3. Expansion turbines 4a and 4b, heat exchangers 5a to 5f and JT valves 6a and 6b are stored in the cold box 2. The JT valve basically aims at controlling a pressure of the compressor. A valve diameter (a Cv value) is determined at a rated flow rate in order to put an emphasis on a controlling characteristic during the rated operation. Due to this fact, when a cooling operation is started, a choke flow occurs, and a sufficient flow rate for a precooling operation may not be assured. If the Cv value of the JT valve is increased in order to keep the flow rate during a precooling operation, a controlling characteristic during the rated operation is deteriorated. Due to this fact, a remote operating signal is shielded at the JT valve and a two-stage motion valve with a degree of opening of the valve capable made larger than normal is employed, resulting in that the JT flow rate during the precooling operation can be assured without damaging a controlling characteristic during the rated operation and the precooling time is shortened and then an operating efficiency can be improved.

Filed: 1988-01-13
Abstract: PURPOSE:To keep the temperature of hat radiation at a predetermined value by detecting the temperature of a radiation heat exchanger and changing the speed of a variable speed motor in accordance with a difference between a detected temperature and a set temperature and changing the blasting quantity of a fan. CONSTITUTION:When a fan 15 starts its rotation, indoor air is sucked up through a suction port into an indoor unit 10, and warmed by an indoor heat exchanger 11 and discharged into the room through an air discharge port 14 in the form of a warm air flow. Upon this occasion, when the blasting quantity of the fan 15 is small, the temperature of a radiation panel 12 further increases and enters an area E, where the detection temperature of a temperature sensor 17 is Th1 or more. When the phase angle of an AC power source voltage becomes small, a drive power with respect to a variable speed motor 16 increases and the speed of the variable speed motor 16 rapidly increases. When the blasting quantity of the fan 15 increases, the detection temperature of a temperature sensor 17 is gradually lowered to shift from a region E to a region D. By this shifting, the blasting quantity decreases and the detection temperature becomes stable in a region C. That is, it is possible to keep the temperature of the radiation panel 12 at a set temperature Ths.
